Merge Risk: 🟡 Moderate · up to Some eligible Swift package runs can require more owned-runner capacity than the planner records or reserves. Update the bounds before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Routing package tests onto reusable machines creates a meaningful trust-boundary change. Forks remain excluded and the job has limited permissions, but the available evidence does not establish how those machines isolate one job from the next. Retained concerns

Count the third side lane in the capacity bounds.
When a full suite has release_build=false and routes the remote daemon, run_plan() includes three side lanes alongside nine admission and follow-on jobs. Its peak is 12, but SIDE_LANES=2 leaves MAX_RUN_JOBS at 11. run_marker() then caps that run’s recorded peak at 11. A compile-only run with all three side lanes can also need four machines while replay reserves only three. Raise the bounds and update the affected capacity tests.

Runner side for the keychain failure is live (teamleaderleo/glaeda#1240, rolled out to all 11 runner hosts): each PR runner job now starts with an unlocked, passwordless Rule from the glaeda docs (CMUX_MINI_RUNNER.md 2h): never store credentials as the cmux user on a PR mini, since anything stored without naming a keychain now lands in cmux-ci, which every PR job can read. |

…ease helper swift-package-tests never reached the owned Macs: all 4 runs in the last two hours were on blacksmith-6vcpu-macos-15. Its only hard need for macOS 15 is the SDK 15 Release Ghostty helper, which runs only on a full suite with release_build. Every other run (a package change under the compile-only policy) is plain `swift test`, which glaeda already classes as light. - pr_runner_pool: a `swift-package` side lane in run_plan when the lane runs and builds no helper (package_lane_owned(); an unknown release_build counts as a helper build). ci.yml passes RUN_SWIFT_PACKAGES and RUN_RELEASE_BUILD. - ci-macos.yml: swift-package-tests takes the picked owned label on attempt 1 (and the rescue's attempt 2 after a refusal) of a same-repository pull request whose owned_jobs names it, with the lane's Xcode; everything else keeps the macOS 15 pool and pin. The rescue already covers it (CI marker). - docs/ci-runners.md: the lane, plus a table of every macOS job and whether it may take an owned Mac. - Tests: picker placement and wiring, dual-Xcode guard, Xcode pin tests.

… bounds - ci.yml passes macos_pr_side_runner to ci-macos.yml, and swift-package-tests takes pr_side_runner before the pool label on attempt 1 and the rescue's attempt 2, like the Claude wrapper and remote daemon lanes (#14431), so it never holds a mini's root runner. - pr_runner_pool: a full suite with release_build false places the package lane as a third side lane, a peak of 12. SIDE_LANES is 3, MAX_RUN_JOBS 12, and FULL_RUN (unknown routing) carries the package lane. The replay charge stays 3 (admission plus the two usual side lanes). - Tests: the release SDK lane, self-hosted guard and change-area checks read the new runs-on and Xcode conditions; picker tests cover the 12 peak and the side-runner wiring.

Goal: every macOS job that can run on the owned minis runs there, with Blacksmith only as overflow. This PR inventories every macOS job and moves the one remaining high-volume lane that the minis can already run:
macos / swift-package-tests. It was 4 of 4 onblacksmith-6vcpu-macos-15in the last two hours and had never run on a mini.What moves
swift-package-testsbecomes an owned side lane (swift-packageinowned_jobs). It is placed only when the run builds no Release Ghostty helper. The helper builds only when a full suite hasrelease_buildon, and it needs an SDK 15 Xcode that only Blacksmith's macOS 15 image has (the minis have Xcode 26.6 alone). In practice that covers every package change under the compile-only policy.pr_runner_pool.run_planadds the side key throughpackage_lane_owned(). An unknownrelease_buildcounts as a helper build, so older callers keep today's plan.ci.ymlpassesRUN_SWIFT_PACKAGESandRUN_RELEASE_BUILD.ci-macos.yml, the job takesinputs.pr_runneron attempt 1 of a same-repository pull request whoseowned_jobsnames it, andpr_refused_retry_runneron the rescue's attempt 2.CMUX_CI_XCODE_APPrepeats the same condition to pick the lane pin. Every other event, attempt or pick keeps the macOS 15 pool and pin; it never readsMACOS_RUNNER_PRor the retry pool.owned-pool-watchalready cover it, because the rescue finds owned jobs by their labels. Main's full-suite dispatch (ci: route main's full-suite dispatch onto the owned Mac minis #14405) is unaffected: it builds the helper, and that PR clears side lanes for main.swift-package-testsaslight: no root token, 1 unit. No glaeda change is needed.Inventory

The minis keep$HOMEbetween jobs and run same-repository PR code, so a shipped binary built there loses ephemeral provenance. A dogfood dispatch can still passmacos_runnerThe same table is in
docs/ci-runners.mdunder "Which macOS jobs may take an owned Mac".Glaeda changes needed for the "could move" rows (not made here)
The glaeda-cmux-runner-hook keys
JOB_CLASSESonGITHUB_JOBalone. It treats an unknown id ascompile, which takes the persistent-dd and root tokens.lint,testandbuildare generic, and test-e2e.yml'sbuild/testare root jobs. The hook needs a workflow-qualified table checked first, keyed on the workflow file fromGITHUB_WORKFLOW_REF. For example,{("cmux-tui.yml", "lint"): "isolated", ("cmux-tui.yml", "test"): "isolated", ("cmux-tui.yml", "cdp-browser-smoke"): "isolated"}. They are cargo and clippy builds into the workspace plus a Playwright Chromium, with no canonical root. The cmux side then needs two things. First, a dispatch side-lane arm in the three macOS matrix rows (attempt 1, behind a new variable). Second,owned_pool_rescue.pyhas to accept aworkflow_dispatchside-lane source, sinceSIDE_WORKFLOW_PATHSexpectspull_requesttoday. That source also has to be added to the rescue'sworkflow_runlist.rerun: it restores a CI product into a canonical root. It needs classproduct, which is inROOT_CONSUMERSand takes the producer's root withglaeda-canonical-root take. cmux also needs to route it to the root label and to stopapp_host_test_rerun.product_runnerfrom mapping owned producers to Blacksmith.release-build: its DerivedData and staging paths need an audit first. If it stays out of/private/tmp/cmux-ci, the class isisolated; otherwisecompile. The picker also needs a key for it.Verification
